Particles and Bubbles Collisions Frequency in Homogeneous Turbulence and Applications to Minerals Flotation Machines
… applications to chemical processes, minerals flotation, food science, and many other industries. In this dissertation, numerical simulations are performed to determine collisions frequency of bi-dispersed particles (solid particles and bubbles) in homogeneous isotropic turbulence. Both direct …

An In-Plant Evaluation of Froth Washing on Conventional Flotation Cells for Coal
Column flotation cells have become increasingly popular in the coal industry due to their ability to improve flotation selectivity. The improvement can be largely attributed to the use of froth washing, which minimizes the nonselective entrainment of ultrafine minerals matter into the froth …

Multiphase Hydrodynamics in Flotation Systems
Flotation is a complex, multiphase process used to separate minerals. Four problems central to the fundamentals of the flotation process were studied. A multiphase grid turbulence experiment was conducted to verify particle collision models. The slip velocities of solid particles and bubbles were …

An Investigation of the Gas Dispersion Properties of Mechanical Flotation Cells: an In-Situ Approach
… parameters affecting the performance of froth flotation cells. However, monitoring, controlling and predicting bubble size is a very challenging task. This dissertation presents results obtained from a comprehensive pilot- and industrial-scale experimental investigation of gas dispersion …

Laboratory-Scale Analysis of Energy-Efficient Froth Flotation Rotor Design
Froth Flotation is an industrial separation process commonly used in the primary enrichment of run-of-mine mineral material. Over the past 100 years, much of the process's development has come from empirical evolution, rather than fundamental understanding. While many of the governing sub-processes …

Development of Methods to Aid in Flotation Circuit Evaluations and Drip Pan Design
… establish the performance capabilities of a new flotation technology for fine coal upgrading, known as StackCell flotation. Flotation release analysis was performed on all samples to determine the amount of hydrophilic material present in the streams around the flotation cell. Data from this work …
